These pictures are a few things I found that are puzzling for me. These were all pretty small, and photographed with the 100X objective. Scales bars are included to give a good size reference.
One species was very abundant and immediately made me think "dinoflagellate" under low magnification. But on closer examination it did not look like the ones I typically find (gymnodinium and peridinium). These were nearly perfectly spherical and without the obvious "plates" and "grooves". The closest "visual" match I could make is a euglena cyst ( see: http://starcentral.mbl.edu/microscope/p ... geid=13248 ), but the color of the ones I found are very much a golden brown, and they move about freely. (Amphidinium perhaps?) Here's a shot of one:
The next puzzler clearly appeared to be euglena, but perhaps encysted in a manner I have not seen before. This "unit" did not move about, although there was slight movement of the individuals inside. Any thoughts as to what is going on here:
The last is another one that I did not recognize. It was not very numerous in the sample but I photographed a couple of them. Suggestions?:
humm... may be the result of meiosis after conjugation?
